Commentary
A CD player equipped with RMS that can be enjoyed by changing the order of songs freely.
It is equipped with a newly developed pickup that realizes a large miniaturization of the optical pickup section.
In addition, the pickup cover is made of a material that is less susceptible to unwanted vibration, and the optical system and disk table are separated into a floating structure to improve trace accuracy and stability.
The digital, analog and power supply circuits are integrated on a single printed circuit board, greatly reducing the need for wire wiring. The board is also fixed in the middle between the top and bottom of the chassis to minimize magnetic distortion.
Copper foil capacitors, large power transformers, OFC power cords, etc. are used, and the output terminals are also gold-plated.
A linear skating system is adopted for the disc set part, and the push loading system which closes automatically when the disc table is pushed improves operability.
Equipped with an RMS function that allows you to program up to 16 songs in the order you want to listen to and play them continuously.
